To all whom iii may concern a citizen of the United States, residing at Eifingham, in the county of Florence and 5 State of South Carolina, have inventedcertain new and useful improvements in Pneumatic 'll'ires and Fasteners Therefor; and I do hereby declare the following to be a full, clear, and exact description of the invenac tion, such will e able others skilled in the art to which it appertains to make and use the same. My invention relates to improvements in tires of that type known single tube, and 1&5 residesin the provision of logs formed on the tire and'adapted to cooperate with specially constructed rim.

An important objectpf my invention is the provision of a device of the above menso tioned character, comprising lugs formed on the tire and adapted to cooperate with recesses' formed in the rim, and means for loclr ing the tire upon the rim.

A. further important object of my inven tion is to construct a device of the above mentioned character, which will be reliable and efiicient in its operation and may be constructed of few parts, thereby lessening the cost of manufacture. to The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which to is appended'hereto and forms a part of this application.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, to and throughout the several views of which similar reference numerals designate corresponding parts: Figure l is a side elevation of my tire and fastener therefor as sembled, Fig. 2 is a transverse sectional view at taken on the line 2-2 of Fig Showing.

the removable plate in its operable position, Fig. 3 is a similar View, taken onthe line 33 of Fig. 1, Fig. l is a detail perspective view of a portion of the rim, showing one 50 of the centrally disposed circular recesses therein, andFig. 5 is a detail perspective view of a portion of the rim, showing the laterally extending recess and the removable platesecured to the rim.

555 Proceeding now to the description of the drawings, the numeral 6 designates as an Specification ot-tetters Eatent. aspire-sass also. my is, rare. serial No.

a min rasrrnnn r or as" or test llrenn. a. at

entirety my specially constructed tire which is provided centrally of its under surface with a plurality ot rectangular logs Y, arranged in spaced relationship.

The rim, designated 8 entirety, is provided with a plurality oi rectangular cess'es 9 centrally thercoi upr 1 face for a distance equivalent ha J circumference. Each oi the cen posed :ect'angulh a the same spaced relation as the formed on the tire 6. The other halt o rim 8 is provided with plurality oi it distantly spaced lateral recesses l d, corn on municating with the atmosphere adjacent one of the side edges or: the rim ll.

A. semicircular plate ll is removably secured to the rim 8 adjacent the portion the wheel which is provided with the laterally extending recesses 10, and is adapted to close the side openings oi the recesses 10. A bolt 12' is inserted transversely thrct the rim 8 and removable plate l. and adapted to receive the nut 13 upon one tere minal thereof to hold the plate ll in cn-- gagement with the rim 8. it is obvious any suitable fastening means may be em.- ployed in connection with securing the plate 11 to the rim 8, and that the illustrated i'orni is the preferred embodiment of the same.

in -assembling the tire, the operation may be briefly described as follows: Certain of the lugs 7 formed on the tire 6 are fitted Within the rectangular recesses 9 which are. so disposed centrally oi the rim 8, whereby the other lugs of the tire are in proper spaced relationship with the laterally extending openings 10. The lugs adjacent the side openings of the laterally extending openings as; 10 are then titted "within them andv the plate 11 is bolted, or othervvisesecured, after the manner described to the rim 8 adjacent the side openings or" the recess 10; whereby tire is locked against accidental derangement from the rim. 8. lit will thus he s in that an eii'icient and reliahle'rncans for toning the tire of my improved construction to the tire rim is provided by the cooperating action of the tire and rim aforementioned. c

In reduction to practice, l: have found that the form of my invention, illustrated in the drawings and r ferred to in the above description, as the preferred embodiment, iatheinost criicicnt and practical; yet realthat the conditions concurrent with struction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing any of the advantages of my invention, as defined in the appended claim.

Having thus described my invention, what I; claim is:

The combination With a tire of a plurality v of rectangular spaced lugs formed integral therewith upon the inner side thereof, a rim provided upon half its circumference with a plurality of spaced rectangular recesses disposed centrally of the side edges of said rim and upon the other half of its circumference with a plurality of spaced laterally extending recesses open at one end adjacent the side edges of the rim and closed at its other end adjacent the other side edge of the rim, said lugs adapted to be. fitted Within said recesses, a semi-circular plate removably mounted upon said run ad -acent the open ends of said laterally extending recesses and disposed flush at its inner and outer termin als with the inner and outer faces of said mm.-
